構造を変更して圧損を下げることは難しいため、濾過度を落とすことで圧損を下げるしかないと考える。
それぞれのCASEは下記の条件で検討をしています。
ディスタンスバーとリングの厚みを変更した場合
エレメント内部のメッシュの厚みを変更した場合
CASE3およびCASE4はエレメントを薄くしてエレメントの組込み枚数を増やすことで初期圧損を減らそうとしたが、
ろ材にかかる圧損の減少よりも、構造圧損の増加の方が大きくなった。
上記の計算は概算です。実際の条件によって計算値が変わる可能性があります。

As it is difficult to reduce the pressure loss by modifying the structure, the only possible method must be lowering the nominal filtration rating to reduce the pressure loss.
We are considering the following conditions for each CASE.
When the thickness of the distance bar and the ring is changed
When the thickness of the mesh inside the element is changed
For CASE3 and CASE4, we tried to reduce the initial pressure loss by increasing the number of the elements to be included, but the increase of the structural pressure loss exceeded the decrease of the pressure loss against the filter.
The calculation above is an estimation. The value may change depending on the actual condition.

As it is hard to change the structure and reduce the pressure loss, it is but to lower the pressure by lowering filtration.
Each CASE is being considered under the following conditions.
When changed the thickness of distance bar and ring
When changed the thickness of the mesh inside the element
CASE3 and CASE 4 are with think element and we tried to the initial pressure to lower by increasing the amount of elements, more than lowering pressure to the filtration, system pressure increase was higher.
The above calculation is rough. There is a possibility of changing calculation value by actual conditions.

Since it is difficult to change the structure to decrease the pressure loss, I think we should decrease the pressure loss by dropping filtration degree.
We are considering each cases in the below condition.
In case that changed the thickness of the distance bar and ring
In case that changed the thickness of mesh in the element
In CASE3 and CASE4, we tried to decrease the initial pressure loss by reducing the elements to increase the number of element installation, however, increasing the structure pressure loss is bigger than decreasing the pressure loss on filter media.
The above calculation is estimation. The calculation value may change depending on the actual condition.

It is hard to decreasing pressure loss with changing the structure , it will be done by decreasing the filtering ratings. CASE for these are to consider for following conditions.
In case of changing the thickness of distance bar and ring.
In case of changing the thickness of mesh at the inside the element.
We tried to decrease the initial pressure loss with increasing the number of assembling the element along with making it thinner for element for CASE 3 and 4, but structure pressure loss is greater than decreasing the chance of loss for filtering.
Above are the rough estimate. It may change depend upon the conditions actually.

Since it is difficult to change the structure to avoid damage caused by compression, it is thought that reducing the degree of filtration is the only way to eliminate damage caused by compression.
Each CASE is considered under the following.
If you change the thickness of the distance bar and ring
When changing the mesh thickness inside the element
In CASE3 and CASE4, we tried to reduce the initial damage bcaused by pressure by thinning the elements and increasing the number of embedded elements.
The increase in structural pressure loss was greater than the decrease in pressure loss on the filter material.
The above calculation is approximate. Calculated values may change depending on actual conditions.
